Abstract :
Aqueous extracts of pomegranate (Punica granatum)peel and seedswere investigatedto evaluate their antibacterialactivity against selected pathogenic microorganisms Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Enterococcus feacalisusing disc inhibition zone technique and the results were compared with commercial antibiotic. The studied extracts possessed strong antibacterial activity against the tested microorganisms. Maximum antibacterialactivity was shown bythepeel extract against Escherichia coli with average zone of inhibition 19.5 ± 0.93mmfollowed by seeds 7.12 ± 0.99mm. The antibacterial activities of peel extract were comparable with commercial antibiotic, Amoxicillin(21.12 ± 0.23mm). Enterococcus feacalis was appeared to be the most resistant with inhibition induced by the extracts of peel 14.87 ± 0.13mmand seeds 7.12 ± 0.19mm.The results revealed that the aqueous extracts of pomegranate peel and seed possessed significant antibacterial potential against food borne pathogens.
